Abstract
A new series of highly efficient, chemically and thermally stable nonlinear optical chromophores have been developed by using a 2-phenyl-tetracyanovinylbutadienyl group as the electron acceptor for a series of dialkyl- or diphenyl-amino substituted thiophene stilbenes. Excellent tradeoffs among absorption, molecular nonlinearity and thermal stability were achieved. Electro-optic polymers based on the guest/host systems and covalent attachment of chromophores onto high temperature polyquinoline backbones demonstrate high E-O activities and good optical, electrical and mechanical properties.
